According to a new study, published in the journal Molecular Psychiatry, playing a video game called Tetris right after a traumatic event, like a car crash, may lower the risk of developing intrusive flashbacks of the event.

Scientists discovered that people who survived a car crash and then played Tetris in the emergency room within 6 hours of their crashes had 62% fewer flashbacks within a week after the event if compared to people who executed another task in the emergency room.

The researchers hypothesized that playing Tetris would disrupt the formation of long-time about the traumatic event, as this game requires the high level of visual attention. The researchers believe that “Tetris” uses up some of the same resources in the brain needed to keep visual memories of traumatic events.
